Detection of Human SOX5 by Western Blot. Western blot shows lysates of human lung tissue and exponentially growing LNCaP human prostate cancer cell line whole cell extract. PVDF membrane was probed with 1 µg/mL of Human SOX5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5286) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for SOX5 at approximately 80 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
